Reef to freshwater tank
So today, I was looking at my 55 and realized how small it is, not length wise but depth wise. So sticking with a 4ft tank, I wanted something deeper and decided a 90 would be good. I recently picked up an older 135 gallon tank but its pretty heavy and I don't wanna risk over 2000 lbs on 2 joist. Anyhow, my friend has a 90 reef tank he said he would trade me for the 135.
Question is, how bad is it to switch to a freshwater planted tank? How would I clean it?
